14 Claims. (Cl. 229-29) This invention appertains to cartons and similar receptacles and more particularly to a structure of this character that is usually employed in connection with the packing of eggs for the retail market.

It is an object of this invention to provide a collapsible carton which may be easily unfolded and set up, and which, when set up, is provided.

with a number of cells or compartments. It is a particular object of the invention to provide such a carton which may be severed into two or more sections, eacha complete unit in itself, adapted to receive a plurality of eggs.

The attainment of these and further objects oi v the invention will be apparent from the following specification taken in conjunction with the drawing forming a part thereof.

Referring to the drawing: Figure 1 shows a blank piece of pasteboard from which the carton is made;

Fig. 2 shows two partitions used in subdividing the cells;

Fig. 3 is a view of the complete carton rea to receive the 8388;

Fig. 4 is a view of the carton shut; an

-Fig.5isaviewdrawntoasmaller scalethan the other figures, showing the carton separated to form two complete sections.

Referring now to Fig. 1, the general shape of the blank piece of paper, cardboard, pasteboard, or the like from which the carton is made, is shown. The dotted lines indicate the lines along which the blank is creased for folding, while the full lines indicate the lines along which the blank is cut.

The portions into which the pasteboard is divided by fold lines have been numbered 1 to 7. The portion 1 constitutes the locking strip, 2 the cover, 3 and 5 the longitudinal sides, and 4 constitutes the bottom of the carton. Theportion 6 is divided into a number of transverse partitions 8 and 9, connected at their upper front corners to the front side of the carton, and at their upper rear corners to a securing strip 7 which, in the assembled carton, is pasted or otherwise secured to the inner side of the rear wall 3, as may be seen in Fig. 3, when the carton is erected. The partitions 8 and 9 are folded down from a horizontal plane parallel to the plane of thebottom 4 to a plane. at right angles thereto, the folding being done along the line 10. In the construction illustrated it is ,to be noted that there are four transverse partitions 8 on one side of the center of the carton and four transverse partitions 9 on the .othe'rslde of thecenter oi the carton,

the partitions being arranged so that when they are folded into position as shown in Fig. 3, the innermost partition 8 and the innermost partition 9 are adjacent one another. When the partitions 8 and 9 have been folded into the position shown in Fig. 3, the two longitudinal partitions 15 and 16 are inserted into place. The longitudinal partitions have a series of notches or slots therein spaced apart a distance equal to the distance between the transverse partitions 8 or 9, and of a. depth to permit the lower edges of the longitudinal partitions to rest on the bottom of the box when the longitudinal partitions are inserted into the slots 12 formed in the transverse partitions.

In the center of each of the blank portions 2, 3, 4, and 5, there is formed a slit 17. The slit in each of these portions extends to within a short distance of the edges thereof and not its entire width. The cut 1'! in each portion may be one continuous cut or it may consist of a number of perforations. The portions 1 and 'I may also'be cut at their centers for a portion of their width, although these cuts may be dispensed with.

The cover of the carton seen in Figure 3 may be locked in its closed position by engaging the 0 locking tongues 19 beneath the triangular webs defined by the lines- 10 and 11. The'complete closed carton is shown in Fig. 4.

Should a. customer desire onlysix eggs, the merchant may split the carton in'half, to form 5 two complete sections, as may be seen in Fig. 5. The splitting of the carton is accomplished by passing a lmife through the slits 17, and cutting the slits through the entire sides of the carton. It is to be noted that the longitudinal dividing 0 partition consists of two pieces 15 and 16 and upon dividing the carton in two, each section retains its own longitudinal dividing partition. The locking tongues 19 on each side of the center of the locking strip 1 point in the opposite directions. This tends to maintain the carton against unintentional opening during handling, especially when the carton shown in Fig. 4 is being cut in two.

The empty carton shown in Fig. 3 may be col- :lapsed forv shipment by removlngthe longitudi- In compliance with the requirements of the patent statutes, I have herein described a. preferred embodiment of my invention. It is, however, to be understood that the same is shown for illustrative purposes only, and I do not wish to be limited to the precise construction shown.

What I consider new and desire to secure by Letters Patent is:

I claim:

1. A paper carton having walls forming a cover, a bottom and two longitudinal sides, each of the walls being slit transversely at its center, the slit in each wall extending to within a short distance of the edge of the wall, a series of transverse partitions on each side of the center of the carton, said partitions being connected to the carton so as to permit the partitions to swing downwardly from positions in a common horizontal plane to positions in separate vertical planes, the partitions on one side of the center of the carton being arranged to swing in one direction and those on the other side of the center of the carton being arranged to swing in the opposite direction, means on each side of the center of the carton for retaining the transverse partitions in their respective vertical planes, the carton being severable into two sections, each complete in itself, by cutting the respective walls in two along the line of the respective slits.

2. A paper carton having walls forming a cover, a bottom and two longitudinal sides, the walls of the carton being weakened along the trans verse center line of the carton, two transverse vertical partitions adjacent one another and located one on each side of the transverse center line of the carton, additional transverse vertical partitions on each side of the center of the carton spaced from the cover and from each other, thereby forming a plurality of cells on each side of the center of the carton, there being two more transverse vertical partitions than there are cells, two longitudinal partitions, one on each side of the transverse center of the carton, said longitudinal partitions dividing each of the cells in two, the carton being severable into two sections, each complete in itself, by tearing the cover, bottom and sides along their weakened portions.

3. A paper carton having walls forming a cover, a bottom, and two longitudinal sides, the walls of the carton being weakened along the transverse center line of the carton so that the carton may be there torn into two sections, a plurality of spaced transverse vertical partitions on each side of the transverse center line of the carton together with a central longitudinal partition dividing the carton into a plurality of cells arranged in two rows lengthwise of the carton, the several cells in the two rows, save the two cells proximate to the transverse center line of the carton, being separated each by a single partition and the number of partitions being two in excess of the number of cells in such rows, two of the transverse vertical partitions being adjacent one another and on opposite sides of the transverse center line of the carton so that upon tearing the carton in two, said last mentioned partitions each constitute one of the end walls of one of the sections each of which is complete in itself, the two carton sections prior to separation being united immovably relative to each other into a rigid structure.

8. The method of forming'a carton which comprises blanking a. sheet of paper to form a cover, bottom, sides and a Wall parallel to and intermediate the cover and bottom, blanking the intermediate wall symmetrically about a transverse center to form transverse cell forming walls two of which lie adjacent opposite sides of the transverse center of the carton, weakening the cover, bottom and sides between the two transverse walls centrally of the carton to facilitate tearing of the carton in two, and permanently securing the sides together by means of the intermediate wall.
